Yes.  For me, it demonstrated a good reason to wait
for C++ support... :)

"The COM Programmer's Cookbook" provides an overview
of COM, as well as a "tutorial" on how to write COM
objects in ANSI C, comparing it with C++ (which further
demonstrates how much the C++ compiler does for you
in the authoring of COM objects).

It also introduces concepts such as tear-off interfaces
and other "advanced" topics, so it's a good read even
for C++ programmers.

It's at:
